A method of servicing a wellbore within a subterranean formation comprising providing a drill string disposed within the wellbore having one or more tubulars associated therewith and forming one or more annuli around the drill string; placing an insulating packer fluid comprising an aqueous base fluid and a viscosifying agent into at least one of the one or more annuli surrounding the drill string; and performing a drill stem test while the insulating packer fluid is in place. A method of servicing a wellbore within a subterranean formation comprising placing an insulating packer fluid in an annular space between a tubular and a marine riser extending from a surface vessel or platform and a subsea wellhead, wherein the insulating packer fluid comprising an aqueous base fluid and a viscosifying agent and has a thermal conductivity of from about 0.008 BTU/(hr&#xb7;ft&#xb7;F) to about 0.245 BTU/(hr&#xb7;ft&#xb7;F).

Wellbore servicing fluids and methods of making and using same

Cement compositions and methods of their use in subterranean applications include the use of a self-degrading cement composition for use in fluid loss applications. A method includes placing a self-degrading cement composition in at least one fracture of a subterranean formation, the self-degrading cement including a cement composition including an acid-base cement, a particulate filler, and a solid acid precursor. The method includes allowing the self-degrading cement to set in the fracture.
